while using the GPS, it is not working properly. If you are using the location
service eg Google Maps and Apple Maps can never pinpoint the location. For

wrong with the iPhone X GPS. Not only GPS but some iPhone X are also facing
WIFI dropping issue. This is serious issue specially for those people whose business
depends upon GPS/location.
A reddit user reported
the iPhone X GPS issue as: 
Can
confirm I’m having the same issue on my iPhone 8 plus, I’ve sent feedback to
Apple. Seems to be a sporadic widespread issue. I did have the developer build
and the issue was present there, I downgraded to the public beta and the issue
is still there. I had to dig out my old Garmin GPS and update it as I got lost
in a unfamiliar area this weekend due to the bug
.”
Sometimes the GPS seems
to load fine but as you will start the apps using it GPS the iPhone has no clue
which direction I’m actually facing in Google maps and sometimes just shows me
spinning around or showing incorrect rerouting options  The iPhone GPS issue does not seem to be a
software issue and seems to be hardware failure as many devise are reported to
be affected with this. needs to be resolved.
